You can then write really big numbers without running out of space
for example instead of 2300000000000000000000000000
you can just write 2.3 x 10^27

Heights of 10-year-olds, regardless of gender, closely follow a normal distribution with a mean of 55 inches and a standard devi

Svetllana [295]

Answer:

Step-by-step explanation:

Given that Heights of 10-year-olds, regardless of gender, closely follow a normal distribution with a mean of 55 inches and a standard deviation of 6 inches.

If X is height then X is N(55,6)

Z score would be $\frac{x-55}{6}$

$a) P(X$

b) $P(60$

c) Tallest 10% z = 1.28

X score = $48+1.28(6) = 55.68$ inches

d) $P(X$

i.e. 16.37% cannot go on this ride.

In an electric circuit, two resistors with resistances x and y are connected in parallel. In this case, if r is the combined res

Vladimir [108]

Answer:

(D) xy/(x + y)

Step-by-step explanation:

To find r in terms of x and y

Given,

two resistors with resistances x and y are connected in parallel
r is the combined resistance of these two resistors
the reciprocal of r is equal to the sum of the reciprocals of x and y

Then,

1/r = 1/x + 1/y

1/r = (y + x)/xy

Find the reciprocal of both sides

r = xy/(x + y)

The right answer is option (D) xy/(x + y)
